Make the mango salsa: In a medium bowl, combine mango, red onion, jalapeño, cilantro, and red bell pepper. Add lime juice, olive oil, salt, and pepper. Toss gently and set aside to let the flavors meld.
Mix the seasoning: In a small bowl, combine all blackening seasoning ingredients. You will use about 2 tablespoons for this recipe. Save and use for my blackened chicken and blackened shrimp recipes.
Pat the fish completely dry. Toss with the oil, then season to your taste (about 2 tablespoons of the blackened seasoning). Sprinkle evenly over all sides, pressing gently so it adheres well.
Cook the fish: Heat a large skillet over medium-high heat. Add a drizzle of oil if needed. Cook fish in a single layer for 2–3 minutes per side, until deeply golden and cooked through. The fish should flake easily with a fork.
Warm the tortillas: Warm tortillas in a dry skillet or directly over a flame until soft and slightly charred.
Assemble the tacos: Add fish to each tortilla, top with mango salsa, avocado slices, and a drizzle of crema. Finish with a squeeze of fresh lime.
Notes
Dry the fish well - this is key for a good sear
Don’t overcrowd the pan - cook in batches if needed
Let the salsa sit at least 10 minutes - flavors deepen
Warm tortillas properly - it makes a big difference
